Flexi Says: A compound is a substance that contains two or more elements chemically combined in a fixed proportion. While a solution is a homogeneous mixture of two or more compounds in which the dissolved particles are too small to be seen or to settle out of the mixture. In a solution, the substance that dissolves is the solute, and the substance that dissolves the solute is the solvent. A solute that can dissolve in a given solvent is said to be soluble in that solvent. A solute that cannot dissolve in a given solvent is said to be insoluble in that solvent.
